Megavar delivered HV testing and protection system commissioning for the Bluegrass BESS (Blue Grass) project in Queensland's Western Downs, working in partnership with
Specifications
Used for earth grid performance assessment by off-frequency current injection, including fall of potential earth impedance measurement, step and touch voltage measurement, ground potential rise assessment, current split measurement and transferred potential investigation. Applied on transmission and distribution substations, power stations and industrial facilities where accurate earth grid voltage measurement is required in the presence of dominant power frequency noise.
Off-frequency injection testing is core work for Megavar, not an occasional job, and we run the TVM1100 and LCI2000C together on substation earthing assessments regularly. We will advise on test setup, electrode and traverse placement, and interpretation against AS 2067 and IEEE Std 80, which on earthing work is usually worth more than the instrument itself.

Megavar engineers use this unit on commissioning projects across Australia. Hire it from a team that knows it inside out.
All Megavar test equipment is maintained under a documented calibration programme. Instruments are calibrated either by external calibration laboratories or in-house against reference standards that are themselves laboratory-calibrated, with measurement traceable to Australian national measurement standards held by the National Measurement Institute. A current calibration certificate is available on request. If your project requires a specific calibration interval, test standard, or documentation for a client submission, tell us at enquiry on 1300 730 499 and we will confirm what applies before you commit.

It measures voltages associated with off-frequency current injection testing of earth grids, including fall of potential, step and touch voltage, and current split measurements. It is designed to accompany the LCI2000C injection unit but can be used with any off-frequency injection test.
Off-frequency injection avoids the power system’s own 50 Hz noise, which would otherwise swamp the very small voltages measured during earth grid testing. The TVM1100 locks to the injected test frequency, tunable from 45 Hz to 65 Hz in 1 Hz steps, and rejects 50 Hz and 60 Hz noise by better than 70 dB.
It is used for earth grid performance assessment on transmission and distribution substations, power stations and industrial facilities, including fall of potential earth impedance measurement, step and touch voltage measurement, ground potential rise assessment and transferred potential investigation.
It is a digital instrument using digital signal processing, with a trans-reflective colour LCD display, internal data logging and GPS tracking. It is not a fixed-frequency analogue meter.
Yes. It is specifically designed to accompany the LCI2000C injection unit, but its two-channel voltage and current measurement, with simultaneous phase angle display, makes it usable with any off-frequency current injection test setup.
Mitton Instruments TVM1100 tuned voltmeter, test leads and voltage probes, a 12 V DC 2 A charger, and a carry case.
Yes. We offer guidance on how to connect the voltmeter safely, interpret results, and integrate it with your resonant test system setup.
